SteamFirst: Few games begin as subtly as Circuits, a music-based puzzle game. The first thing seen is the developer logo as it seamlessly blends into the menu screen – with only two options. Simple. Brilliant. In the same time frame, a slow, halting, soft and ethereal melody trickles out. Clicking on the “Play” button brings up the game levels screen which is also very cleanly designed, which makes the next steps easy to take.
